When's the last time you played WoW? They added a raid finder for Dragon Soul. It's possible to go in and kill the final boss in less than an hour, if you play your cards right. At most, it might take a few hours, with no previous experience needed. The only reason to keep playing after that is to get more gear, gear that will be outdated by the time the next expansion is released. To me, this is a bad move. The game functions like an assembly line now, and there is no reason to play just for the sake of having fun, especially since everyone is rushing to get everything ASAP and is always in a horrible mood.
I know what you're trying to say, but this line of thinking is flawed. Once something like this is introduced, it becomes standard. Everyone begins to do it that way, due to convenience, and it becomes nigh impossible to find groups the "normal" way. I still have my WoW account active, and I play it sometimes, but I pretty much switched to FFXIV because of how horrible WoW has become. I love my guildmates, but even they tend to do content finder before trying to make a guild group, because it's easier and it gets them rewards faster. Just about every guild I see handles things the same way. All anyone cares about is how quickly they can get the next best piece of gear, so they can wear it while dancing on a mailbox, and they will do ANYTHING in order to get it. This usually includes fighting with people from the moment they enter a randomly assigned dungeon, if they choose to talk at all.
There are some things WoW does right, and I think FFXIV should pick up on those. Mostly in the area of the UI, questing, and a few other things. I'd like to hope that everything else that makes FF what it is will stay, such as attunements, the necessity to work well with others, and the slower pace. Part of what has ruined WoW is the spastic speed at which everything occurs. It ramps people up and makes them not only aggressive, but they expect everything to be handed to them instantly. Add-ons are another issue, and I really hope nothing like Deadly Boss Mods or DPS counters are allowed. That will create even more aggressive behavior and put the devs on a path to making content more and more convoluted.
If they are reading this, I hope they are able to learn from WoW, both by what Blizzard has done well and what they have screwed up. A 100% WoW clone would be a disaster.
